A rare type of acquired internal hernia, the renal paratransplant hernia (RPTH), of which only 11 cases have been reported in the literature so far, can follow renal transplantation. We report a patient who presented with acute abdominal pain and vomiting 6 weeks after renal transplantation in the right iliac fossa. A noncontrast abdominal computed tomography scan showed signs of small bowel obstruction. The patient was taken to the operating room for a midline laparotomy, and RPTH with incarcerated small bowel was diagnosed. The bowel loop was released and found to be viable. The postoperative course was unremarkable. It is unclear whether perioperative peritoneal defects or spontaneous ruptures of lymphoceles into the peritoneal cavity form the basis of this rare type of internal hernia. Surgeons should be aware of this entity and avoid both peritoneal defects and postoperative lymphoceles by paying careful attention to meticulous surgical technique.
